Great thread i really appreciate all the info. To start off, this is my first Audi so i have alot to learn any help would be great. I'm having some issues connecting the dots for the sq5 bbk. Im seeing posts with pictures of the sq5 caliper 345mm brembo (part # 8R0-615-107-A, brembo) on the s4 for the bbk project. So i know the q5 brembos fit but i also saw some places about the 380mm rotors from the sq5 on the b8. Will these 380mm calipers(part #8R0-615-124) from the sq5 bolt on the b8 s4 as long as i have wheel clearance? Which i believe i do, currently running 19x8.5 ultraleggeras, and i saw a picture of someone w 380mm and leggeras. I'm trying to message him but i can't find the same post in the forums. If these are the correct calipers, once last questions what is everyones preference here the brembo 345 or the oem 380?

Side note if this is the wrong place to post this im sorry but felt it would see the most attention here.

Im confused about those numbers. Why were bolts and balancer (?) included in the IE weight but not in the 034 weight?

You need the balancer for the IE pulley to work - its an overlay pulley which utilizes the OEM pulley for the Aux belt and the bigger overlay for the larger crank ratio.

The 034 pulley is a complete 1 piece machined unit.

Bolts might add around 80gms at most.

Thank you for a great starter page and reference points for all of us new S4 owners. I'm looking at upgrading the OEM 6MT shifter in the near future; the prior owner was not kind and shifts are notchy and down right impossible to catch sometimes. I will use your post for pointers and links for the JHM or ECS shifter installation tips.

Cheers.

Hey, here's a list of the mods on my s4 2014. I keep getting this code, already changed both O2 sensor. Happens when I'm going into boost. Epc light will pop up, when I pull over turn off and on, light is gone. Any advice ? Thanks in advance.
